Description: Stroke is a significant cause of disability globally, with ischemic stroke being the most prevalent form. This study investigated face perception in patients with lacunar strokes, specifically examining the ability to distinguish and recognize familiar and unfamiliar faces. We tested 52 patients with lacunar stroke (mean age = 65.97 ±9.96) and 28 age-matched healthy individuals (mean age =66.24 ±10.15). The participants received three face perception tasks: Name that Celebrity, Identity Sorting Task, and Face & Object Solitaire, and were also given the MMSE and mRS clinical assessments. The results showed that the stroke group needed more cues to recognize famous persons than did the control group. For face identity sorting task, both groups were more accurate when sorting familiar faces; however, the stroke group performed significantly worse than the healthy group when sorting unfamiliar faces. For the face solitaire task, the control group outperformed the stroke group, but there were no group differences in the object solitaire condition. Overall, these findings indicate that although the average MMSE score is normal (HC: 28.22, Stroke: 27.96), patients with lacunar stroke have difficulty recognizing famous faces and distinguishing unfamiliar faces. This may reveal a previously overlooked face perception deficit in these patients.
